The rule is:
The ball becomes dead when an umpire calls "Time." The umpire-inchief shall call "Time" --
(a) When in his judgment weather, darkness or similar conditions make immediate further play impossible;
(b) When light failure makes it difficult or impossible for the umpires to follow the play;
NOTE: A league may adopt its own regulations governing games interrupted by light failure.
(c) When an accident incapacitates a player or an umpire;
(1) If an accident to a runner is such as to prevent him from proceeding to a base to which he is entitled, as on a home run hit out of the playing field, or an award of one or more bases, a substitute runner shall be permitted to complete the play.
(d) When a manager requests "Time" for a substitution, or for a conference with one of his players.
(e) When the umpire wishes to examine the ball, to consult with either manager, or for any similar cause.
(f) When a fielder, after catching a fly ball, falls into a bench or stand, or falls across ropes into a crowd when spectators are on the field.
As pertains to runners, the provisions of 7.04 (c) shall prevail. If a fielder after making a catch steps into a bench, but does not fall, the ball is in play and runners may advance at their own peril.
(g) When an umpire orders a player or any other person removed from the playing field.
(h) Except in the cases stated in paragraphs (b) and (c) (1) of this rule, no umpire shall call "Time" while a play is in progress.
Clearly J.A. Happ was incapacitated, but you rarely see this called. I'm not sure why not, I would think that you, especially on a play like that, you would want to stop play so that the player in trouble can get help as quickly as possible. It seems that Happ will be ok, but, at the time, it looked like it could be very bad.
Personally, I'm always on the side of making sure the player is ok, the umpires can figure everything out after that, place the runners where they deem best, but let help get to the player rolling around on the ground as quick as possible.
In this case, Encarnacion went and got the ball, and got the play stopped but, had the umpires called right away, the trainer could have been there that much sooner.
Anyway, let's have a poll.
